Is this correct for the updated blade guard on a radial arm saw?

The carriage doesn’t go back far enough for the blade guard to fall down behind the fence. I thought the guard was supposed to keep the carriage in the home position until the user lifts it with the lever on the handle. I’m wondering if I did something wrong. Any RAS users know what I’m talking about?

    It’s honestly really impressive seeing the SawStop table saws stop. If I’m reading it right, they use capacitance to detect a body part and take advantage of the space below the table to let the blade fall into while braking it.

      Yeah the SawStop technology is really cool and it’s too bad that it’s held up by patents. In my case, because of budget and physical space constraints, the RAS turned out to be the right choice for me.

        I thought they announced they were making the patent public so other companies could make the blade stop mechanisms and hopefully save more lives/body parts

          Stumpy Nubs has released a video on this topic, which is what I’m mainly pulling from.

          Several of SawStop’s patents have expired but there is one still active which is fairly broad in scope and basically gives them right-of-way over any flesh-detecting saw brakes. They sued (or issued a cease and desist, don’t know if it went to court or whatever) Bosch for the line of flesh detecting saws they briefly sold. There is now some proposal for requiring all saws to have flesh-sensing blade brakes in the US, which would basically set the minimum price of a table saw at $1000 or more, and SawStop has “promised” to open their patent if this becomes law. For whatever that’s worth.

          It is my understanding that Underwriter’s Labs is where the requirement for any new model of table saw sold after 2008 have a riving knife.
